Assuredly We vouchsafed the Book unto Musa; so be thou not in doubt in thy receiving it. And We appointed it to be a guidance unto the Children of Is'rail. 23 We appointed leaders from among them, guiding by Our command when they were steadfast and when they had firm faith in Our signs. 24 Surely thy Lord will distinguish between them on the Resurrection Day, touching that whereon they were at variance. 25 Did they not find guidance in the many generations We had destroyed before them, over whose dwellings they (now) walk? There were indeed signs in this. Will they even then not listen? 26 Do they not see how We drive the water to the parched lands and bring forth therefrom crops from which their cattle and themselves eat? Will they not see! 27 They also ask: 'When will this Opening come, if what you say is true' 28 Say: "On the Day of Al-Fath (Decision), no profit will it be to those who disbelieve if they (then) believe! Nor will they be granted a respite." 29 Therefore turn away from them and wait as they are waiting. 30
